Application filed August 22, 1916. Serial No. 116,281.

To all cl2/1.0m t may concern.'

Be it known that I, JOHN A. FERGUSON, afcitizen of the United States, residing at Denver, in the vcounty of Denver and State of Colorado, have invented certain new and useful Improvements in Molds for Tiles, of which the following is a specification.

My invention relates to improvements in the manufacture of tiles from a suitable plastic substance, and while it is-particu-V larly designed for making'rooing tiles from a cementitious mixture, it will be understood that the word tile as herein used, is not limited necessarily to a roofingtile, but includes analogous articles, wherein a similar element is laidin overlapped relation to another, 'as in tiling generally. l

As such mixtures have a decided tendency to'settle, when in a fairly liquid state, I

have found that, in making these more or less fragile articles, it is of great advantage to mold each tile facing downward in a settling pan. f

The primary objects of this invention,

therefore, is., to preserve the superior qualityV -of such tiles as to uniform coherence and finished facing, and by providing a special series ofmold elements, to produce a number of the tiles at substantially one operation, and in a novel manner with a` minimum of time, labor and expense.

Other objects and advantages of the invention will hereinafter appear and the novelV features thereof will be particularly pointed out-in the appended claim.

rlhe invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which- Figure 1 is a vertical longitudinal section through a plurality of pans with the tile or .shingles molded and ready for removal.

Fig. 2 is a perspective view of one of the pans.

Fig. 3 is a perspective view of the under side of the bottom of the pan.

Fig. 4 is a perspective view of one of the completed tile or shingles.

Like numerals of reference indicate like parts throughout the different views.

Referring to the drawings:

1 designates a pan of suitable material, preferably metal, the bottom of which upon its upper face is provided with one or more transverse grooves 2 of any suitable contour,- forming upon the under sidel thereof the corresponding ridges 3, see Fig. 3. vThe bottom of the pan upon its upper face is formed with longitudinally extending ygrooves 'aforming upon the under side of the:bottomrof the pan the corresponding ridges 5, see'falso Figz;r The side and end walls '6 of the pany are inseparably associated with its bottom, and preferably flare'upwardly therefrom, as shown, to facilitate removal/of vthe molded article and one of wall, is `shown as provided with la slight edge recess 7 for a purpose which will hereinafter appear. j In some cases I may provide teats or the likeSprojecting rupward from the bottom at one end, as seen inFig. 2, for the purpose of producing 'nail holes rin the molded article. These'teats or projections may betapered in some cases to provide tapered openings in the tile or shingles. *l

The surrounding marginal ledge 9 forms a rest' or support for the pan, which pan is shallow, being substantially of a depth correspondingto the desired thickness of the molded, article. In some instances I provide the pan with one or more inserts 10 at a corner or corners, which inserts may assume a shape corresponding to kthat desiredy to be given to the corner or corners of the molded article. In

the present instance I have chosen to show them as beveled, see Fig. 2, to provide correspondingly beveled faces 11 at one end of the tile, as shown in Fig. 4.

Having a plurality of panssubstantially as above described, the tiles are molded as follows: A pan 1 is placed upon a suitable support. Plastic material 12 is then placed in this pan and then another pan 1 filled with plastic material is superimposed thereon, and then another likewise filled placed on top of that, as seen in Fig. 1, and the same procedure followed until the requisite number of pans are in position. The material is then allowed to set or harden suii-y ythese walls, in the presentinstancean end 1 When the article isbeing molded.

means of a suitablereinforcement. as shown' at 1&1 in Figs. 1 and 4:, molded into .the plastic material, as will be readily understood upon referenceto Figi. s f

I may sometimes .provide securing strips for thetiles, such as shown .in Figs. l at 15,

. the said strips being molded into: the tiles and provided inthe presentinstance lwith slots 16 of substantially keyhole shape to receive the securing means and to permit of realdy lremoval of the tiles when necessary.

The securing strip may be molded into eitherv end of the tile.` In some instances it is'useful at koneend and in some instances atthe other end. Both the nail holes and the securing stripmay be present in the one tile or I may omit either as may be found most desirable.

Either or both ends of the pan may be provided ywith a recess 7 hereinbefore referred to to receive the securing strip 15 In some instances this securing strip is molded into the end adjacent the inserts and in some instances at the yother end. `The pans; are correspondingly provided with recesses 7.

The ridges and depressions of the completed molded articles are clearly seen in Fig. V1. In Fig. 4 the longitudinal ridges17 and thetransverse ridges 1S are clearly illustrated.

' of equivalents as may fairly come Within the scope of the ensuing claim, the essence 'of the invention residing primarily "in4 the fact that I mold'the tiles face downwardly, the top of the tile being formed, in molding, with transverse and longitudinal edge beads, and the bottom'thereof With' corresponding grooves, disposed in true complementary alinement with said beads.

Having thus described my invention, what I claim is :-v

In molding apparatus for tiles substantially as set lforth, a plurality of shallow mold pans, of uniform dimensions, each having aclosjed bottom, inseparable upwardly Haring ,end and side Walls'providing an unobstructed open top, and a laterally disposed external marginal flangesupport, the closed bottom being suitably depressed to provide transverse Aand longitudinal pattern grooves along the inside face and congruent pattern beads on the outsideface thereof, said grooves land beads being 'formed contiguous t0 but independently of their complementary end andside walls and disposed wholly Within the bounded area ot' said open top, and the several elements 'functioning in ope-ration, substantially as described.

In testimony whereof 'I affix my signature inthe presence of a Witness.
